A man observes a balloon at a 62° angle of elevation. He knows the balloon is hovering directly above a point on the ground, 900 feet to the east, as shown in the figure below. sin 62 0.8829 Cos 620.4695 tan 62 1.8807 6 ft 900 ft If the man is 6 feet tall, what is h, the altitude of the baloon, to the nearest whale foot?

Ratios

A ratio is a comparison between two numbers of the same kind. It represents how many times one number contains another. It also represents how small or large one number is compared to the other.

Trigonometric Ratios

Trigonometric ratios give values of trigonometric functions. It always deals with triangles that have one angle measuring 90 degrees. These triangles are right-angled. We take the ratio of sides of these triangles.
